For example, in this circuit (simplified case of a … WebSaturation — output voltage is limited to a peak value, usually slightly less than the power supply voltage. Saturation occurs when the differential input voltage is too high for the op-amp's gain, driving the output level to that peak value. Slewing — the amplifier's output voltage reaches its maximum rate of change.

WebThe Inverting Operational Amplifier configuration is one of the simplest and most commonly used op-amp topologies. The inverting operational amplifier is basically a constant or fixed-gain amplifier producing a negative output voltage as its gain is always negative.
